• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programaaaadas draw codigo.\"))) OR (\"programaaar plc codigo.\"))~".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programaaaadas draw codigo. ))) OR ( programaaar plc codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programaaaadas draw codigo."))) OR ("programaaar plc codigo."))*.
